Yeah, so my server goes full retard every so often and decides to let players duplicate blocks every so often. A reboot usually temporarily fixes the issue, but the issue randomly persists every so often. It seems as of lately the bug only takes place in the nether, but it has too taken place in the overworld. The bug goes as follows: A user places a block, and it immediately reappears in his inventory. However, the block still remains in the world, allowing mining for infinite duplications. However! I have noticed that when I move roughly 100 blocks away from an area where I am able to duplicate, the bug disappears. Very strange indeed. I have no confirmation if this works on the overworld. These are my plugins: TimeTheEnchanter ChairCraft LagMeter HeroBounty TerrainControl LWC Appleseed BorderGuard EventsPlus GravelClay Turnstile OpenInv BKCommonLib mcbans Tombstone Tables EnchantMore FalsebookCore mcMMO Essentials NoLaggTNT NoLaggItemBuffer WorldEdit FalseBookBlock EssentialsSpawn VanishNoPacket SignShop FalsebookIC FalseBookExtra Factions Phew... that's a lot... Anyway, help is much appreciated!!
